The new King of the AI ​​Open Source is Alibaba. And its strategy is simple: to be tired

by

Alibaba qwen3 -omni has become the new jewel of the AI ​​Open Source segment. This model, launched last week by the Chinese giant, manages to compete in various benchmarks with some of the best models of OpenAi or Google. But the important thing is not so much as the fact that it alibba Not stop taking AI models at a frantic pace and almost strenuous. QWEN models succeed. The QWEN3-OMNI-30B-A3B-INSTRUCT model is one of the variants of the QWEN3-OMNI family newly launched by Alibaba. This version has become the most popular model in the Ranking of available models in Hugging Face. Since it appeared there, almost 100,000 times has been downloaded, but it is not alone. The new QWEN3-Max-Thinking manages to match or overcome models such as Grok 4 or GPT-5 Pro. They do not stop launching models. As they point out In SCMPto date Alibaba has published more than 300 Open Source models that have served for other developers and companies to launch their own. In fact, it is estimated that there are more than 170,000 derived models, which seems to have managed to have Alibaba right now the world’s largest ecosystem. The data were shared in The APSARA conference Organized by Alibaba Cloud in Hangzhou last week. Some recent examples of that frantic rhythm: Alibaba Copa the ranking. Although they were released in April, the QWEN3 models have not stopped renewing in recent months with new capacities in the generation of text, images, audio and even video. The improvements in multimodal behavior have helped create this new “OMNI” family – which precisely handles all kinds of entrances and exits – and with it with it returns that yield They even rival with the best proprietary models of firms such as Google and Openai. Models for all tastes. If one looks That rankingfive of the first 10 models are from Alibaba. Tencent has two others, IBM Granite surprises in fourth position and also We have Deepseek-V3.1-terminus Already a voice text model called VoxCPM. Source: The Atom Project. Llama, missing. Meanwhile, the traditional dominator of said scope, The Meta Llama Modelis totally missing from the first positions of this ranking and appears in position 41. OpenAI and its GPT-Oss-20b model It is also quite displaced (position 30). The responsible for The Atom (American Truly Open Models) Project recently revealed A study in which they highlighted how accumulated discharges of Open Source models already come from Chinese models than US models. Llama was the most downloaded open model until recently. Now that position is occupied by the Models of the Qwen family of Alibaba. Source: The Atom Project. Be careful, downloads are something else. It must be said that the ranking focuses on “trending” models, that is, those whose recent popularity is high. The Openai model has in fact downloaded 6.71 million times, while Alibaba’s most downloaded model is QWEN3-Next-80B-A3B-Instruct, with 2.63 million downloads. Llama-3.1-8b-Instruct surpasses both (for now) with 7.18 million. In The Atom Project, yes, they point out that the accumulated discharges of the different flame variants have just fell below those of the Qwen variants. The reason is simple. Alibaba does not stop getting more and more models. Alibaba’s strategy has been overwhelming, and since in April it launched the first QWEN3 models, it has not gone from maintaining a frantic pace of launching of improved and derived versions such as QWEN3-Next, QWEN3-OMNI or QWEN3-MAX, in addition to specific models for generation of images as qwen-image-editordirect competitor of the famous Nano Banana, from Google.

A Spanish company wants to convert the chitamiedos into biker allies. Promises to be as simple as effective

by

We are not going to discover anything if we say that chitamiedos are one of the great dangers for motorists and cyclists. For years solutions of all kinds have been sought. Among them have been proposed and installed Save them With double protection, Some even padded To absorb the impact and above all, eliminate the blade effect from the supports. There are also tubular options that follow that same logic of double and lower protection but avoiding the small pillars that can curtail members. Now, a Spaniard has presented a new addition that does not imply a new design of the cloakrooms. In this case, the objective is that emergency services can act faster and, therefore, some times that can be crucial when an accident is suffered. A connected alternative The system is called Plugsmart Pro And it is devised by the University University of Valencia (UPV) in collaboration with the Valenciana Metalese company is based on a similar idea. In this case they use artificial intelligence, environment monitoring systems and bidirectional signaling to alert drivers in real time. The system Analyze Constantly what happens around them and changes their lighting to warn drivers, bikers or cyclists that they approach a dangerous place, in complicated conditions or that there is some obstacle along the way. To do this, use some lights connected to each other that are installed on the wore. These emit a certain halo of light but when the weather conditions are complicated, the light takes strength. It is the simplest function because the truly interesting is in the monitoring of the environment. If the guardraíl detects that another vehicle is approaching, the flashes become more visible to alert who is on the other side of the curve. Also if, for example, there is a damaged vehicle, an injured person or an animal is crossing the road. If the system detects a dangerous object, the intensity of light increases. The invention has won the Ponle Brake Prize for Innovation in Road Safety in 2024 and this year the National Award Award for Conservation Safety. The companions of Motorpasion motorcyclethat from the DGT have already shown their support for the system. And it is that when the last great advantage of the system is that it can notify emergency services in case of accident. The latter is one of the incentives that the DGT has wielded to convince us that the V-16 lights that will be mandatory as of January are better than the classic triangles. That is, the system alerts drivers, cyclists and motorists that They approach a danger and its light adapts to signal its risk. But, in addition, it comes into contact with the authorities in case of detecting a blow with the intention that the response time from the accident warning to its performance is as much as possible.

Chinese researchers believe they have discovered a simple “trick” to lose weight: eat raw vegetables

by

For decades, scientists have discussed the effects of vegan and ovo -vegetarian diets on weight loss and heart disease prevention. Without much success, really. Not because The clues in favor have not accumulatedbut because something was missing. A common link, a thread that organized all that scientific evidence and gave meaning. In recent years, a team of doctors from the Qilu Hospital of the University of Shandong He thinks he found That piece that was missing. And it’s an important piece. Above all, because obesity is becoming The great epidemic of the 21st century. 1.9 billion overweight peoplesome 600 million people with obesity and up. Something that would not be a problem if it wasn’t because, like They wrote Yani Xu and his team in their research, “obesity and its associated complications not only lead to an increase in morbidity and mortality, but also to a reduction in quality of life.” Finding simple weight loss strategies goes beyond aesthetics or fashion: it is an investment in quality of life. But did not solve Ozempic? It is true that the arrival of Ozempic (and the rest of New agonist medications from LPG-1) has radically changed our way of seeing overweight: as Antonio Ortiz said, these medications are helping us understand that Metabolism and appetite are biological facts, not moral elections. Biological facts that, as we see, bring huge social consequences. Plan b. Therefore, although the “new ozempics” are being revolutionary, they are far from being the solution to all our problems. Not only is these very expensive medications (and obesity shows a clear correlation with greater rates of poverty and precariousness economic); They are not substitutes for healthier and more balanced habits. That’s where Yani Xu and his team enter. In search of lost evidence. Tracking in the previous bibliography, Chinese researchers found 24 studies that followed more than 2,000 people. They were quite quality studies (randomized clinical trials) and that has allowed them to conclude that there was a detail that showed very strong links with a lower risk of obesity and heart problems: raw vegetables. In fact, this is true even when they eliminated the effect of genetic factors from the equation. Something not too common and, therefore, very interesting. “The vegetarian diet is a viable option for people who wish to control their body weight and (prevent) metabolic diseases,” They explain. How is it possible? The researchers They shuffle some ideas: From its high content of phytosterols and fatty fats to its role in reducing inflammation and oxidative stress. However, it is not too clear: we have a statistical explanation, but we still lack a mechanism of action. We may have solved one of the big problems when establishing a clear relationship between weight loss and veganism, but not at all. However, with the data that Let’s have on the tableit seems that the idea of ​​progressively increasing the weight of vegetables (and raw vegetables) seems like a positive strategy. More positive than we thought.

Emptied Spain has been filled with solar mills and panels, but waste energy for a simple reason: there are no cables

by

At noon, the sun and the wind are left over in the emptied regions. At dusk, the cities turn on the gas. Spain has run more than anyone raising renewables in the unpopulated territory, but the cables that take them to the demand are not tended at the same speed. The result is a broken bridge: clean energy is born in emptied Spain and does not arrive, when it is necessary, urban Spain. Today, for the first time, the distributors have published the “Map of Plug” for new demand: the photo is stark. The expected map. By mandate of the National Commission of Markets and Competition (CNMC), the great distributors —I-de (Iberdrola), e-Distribution (Endesa), UFD (Naturgy), E-Redes (EDP) and Repsol Distribution— They have published the capacity maps To connect new firm demand to the distribution network. It is an radiography where they show, knot to knot, where there is a hole, what is busy and what is in process. According to the employer Aelēcthe first results confirm that 83.4% of knots are already saturated, which prevents connecting new consumptions such as industries, data centers, storage or electric vehicle recharge. The association itself defines it as “transparency milestone”, but warns that, under these conditions, without investment, the transition is raised. The great territorial neck. Here is the core of the problem. Spain has installed renewables where there is resource and soil: rural regions with low density and little network. However, demand grows in cities: metropolitan areas, logistics corridors, data clusters. In the middle there is an electrical system that does not endure that mismatch, since transport corridors are missing to evacuate surpluses and, above all, distribution capacity to connect the new demand where it is requested. The result is that at noon there are many cheap MWh that are cut or sold at zero price; When the sun falls, the network needs support and the gas enters, Based on pool. The double face of emptied Spain. If the anticipatory network is not remunerated and planned, there will be no industries, CPDs, or recharge of electric vehicles, or hydrogen or storage projects that create employment and set population. But if investigated without criteria, the cost will fall on rates without effective use. The key is agile planning, clear priorities and mechanisms that accelerate reinforcements where demand is plausible: poles such as Aragon, but also Extremadura, Castilla y León, Castilla-La Mancha or inner Andalusia, where hot knots and curtailment-up to 30% renewable wasted by saturation– They are already common. The demand boom. There is a very illustrative fact: The increase in data centers. Applications to get an access point have multiplied by 80 compared to previous years, According to the Spanish. Among them are technological, great consumers and promoters of hybrids that seek to consume in situ. Aragon has become an epicenter. Only the projected data centers would add more than 2 GW of requested power, with Amazon Web Services, Microsoft or QTS/Blackstone at the head. In this new scenario, the race for a “plug” is no longer limited to first: weigh guarantees, guarantees and project criteria. “Historic traffic jam.” The “complete maps” – without significant hollows – stress even more the pulse with the CNMC. The fear of the sector is double: losing industrial and digital projects (including CPDs) for not being able to connect them and see investment relocation if the jam persists. The electricity story connects that urgency with the regulated remuneration: they argue that with a rate of 6.46% the volume of reinforcements required by the demand wave required, and remember that in other countries (Italy, United Kingdom, Sweden) the reference rates are higher; In Spain, they ask around 7.5%. For its part, the CNMC two proposals presented in July: a financial compensation rate of 6.46% by 2026-2031 (from current 5.58%) and a new distribution methodology that turns towards the Totex model (CAPEX + OPEX). This system includes incentives for efficiency and quality, and league part of the remuneration to the contracted power, to avoid overrredes that end up paying consumers. The regulator insists that the framework must encourage investment without compromising the affordability of the invoice. The forecasts. Access to the distribution network no longer depends only on the order of arrival. The processing requires guarantees, technical draft and guarantees, and a period of one month to present the documentation after reserving a point. The resolutions should be issued in less than six months, with technical support for Red Electric. In addition, scores that value CO₂, investment volume and speed at the beginning of consumption are applied. In parallel, solutions such as battery PPAS arise, which allow to finance storage and take advantage of the cheap electricity at noon at the afternoon, avoiding the resource to gas. But without broader investment limits, as Aelēc claimsthe bridge between rural Spain and urban Spain will remain broken. The PNIEC foresees more than 53,000 million in networks until 2030, although the CNMC defends to maintain the rate at 6.46% for efficiency and affordability, while the sector asks for greater certainty and return. The political context adds pressure: after the rejection of the “Decree antiaps” In July, the dilemma is sharpened. The end point. Spain does not have a sun or wind problem; It has a bridge problem between where it occurs and where it is consumed. Capacity maps have made what the industry had been suffering: the distribution network is at the limit. Without a jump in investment and planning, the transition will be stuck where there are less labor and more territory. If the network does not reach empty Spain, clean energy will not reach rich Spain. The choice is not whether to invest or not, but how, where and with what rules so that the cost does not pay it neither the countryside nor the city, but the economic future of both.

the problems of referring to the AI ​​as simple as recognizing a photo of Francoism

by

An image of a humble Spanish family in the 50s has recently become the epicenter of a viral controversy in X. The photograph It ended up unleashing the hysteria of many users, a hysteria caused by blind trust towards the responses of artificial intelligence, in this case that of Grok. Another example of verifying historical information with AI has its things. What happened. It all started when the @kritikafull user public A black and white photograph of a family in poverty conditions, accompanied by the following phrase in an ironic tone: “We lived better.” The image generated thousands of visualizations, but also aroused the interest of many users who doubted that photography was taken in Spain and ended up resorting to Grok, as usually happens lately on the social network, to verify the information. The origin of the controversy. Image: Arenas Photographic Study A problematic answer. Grok I identified erroneously Photography as an image taken during the great American depression, attributing it to photographer Walker Evans and stating that he showed the Burroughs family. This answer He replied massively In dozens of publications that accumulated thousands of visualizations, making the error an apparent truth that served to discredit the original publication. A research work. The user @ropamuig37, who describes herself in her profile as a historian, decided to verify the facts by one Inverse image search on Google Lens. The result took it directly to the photographic file of the University of Malaga, where the image appears perfectly classified as “Housing, August 1952, Malaga, Spain”. Photography is part of a series of reports that includes Spanish housing of the time. If AI says no, I believe it. When the historian gave Grok the real documentation, artificial intelligence He was inflexible For hours, insisting that it was an “UMA error” and maintaining that it had “verified” the similarity with the American photo. Even after the historian gave him obvious visual direct and comparative links, Grok took almost two hours to recognize his mistake. The damage was already done, since the publications that took the verification of Grok ended up flooding the social network with thousands of visualizations. Meanwhile, the real verification of the historian (and other users such as @Remusokamias it reminds us in their thread) barely accumulated at the beginning a fraction of what the rest of the publications that viralized Grok’s wrong response achieved. A major problem. On the platform The use of Grok has been normalized To perform all kinds of checks before user publications. “Grok, explain this” or “Grok, is this right?”, They are increasingly common expressions in X, where millions of users have begun to delegate to the verification and understanding tasks that traditionally required to contrast diverse sources. And of course, at least today, blind trust in these tools can generate Large -scale misinformation. We have already lived it over the last years after the AI ​​boom, a consequence that, given the growing refinement of these tools, goes to adults. In polarized contexts when any information can be instrumentalized politically, AI can also become a dangerous tool. Especially for its ability to Generate quick and verify responses to contrast certain facts. Luckily, this case has not been serious, but reflects the massive adoption of AI tools and how much we begin to trust them.

The last O2 movement is not a simple rate change. It is an unexpected turn that can shake the market

by

O2 has surprised us this week with a change that, although it seems small, tells us a lot where the operator is directed inside The new telephone. A rate It has disappeared From its catalog, and with it, O2 has eliminated the 300 Mbps of its offer and the possibility of hiring fiber and mobile for 30 euros per month. It is not good news for the market, let’s see why. Goodbye at 300 Mbps. O2 decided to charge a few days ago the fiber combined of 300 Mbps + two mobile lines of 10 GB and 30 GB, and also eliminated the possibility of hiring only 300 Mbps fiber. The only option that remained with that speed was the fiber combined 300 Mbps + Mobile 50 GB for 30 euros per month. That rate has disappeared this week, so the minimum speed that O2 offers throughout its catalog has become 600 Mbps. It doesn’t matter if you want only fiber or mobile fiber, you can no longer have 300 Mbps. It is only possible to choose 600 Mbps or 1 Gbps, just like Movistar. A higher input price. By eliminating that package of 30 euros per month, the most cheaper fiber and mobile team of O2 costs 35 euros per month. Of course, you have two modalities to choose from that price: 600 Mbps + 60 GB mobile fiber. 600 Mbps + Mobile 10 GB + Mobile 40 GB. These two plans offer twice as a speed and more gigabyes that the rate eliminated by a little more, yes, but there will be those who agree with those 300 Mbps to pay 5 euros less. When an operator eliminates its cheapest plan, the access price is more expensive to its products and that is never good news for the user. Quiet, O2 is not going to upload the price. The strategy of O2 goes to keep the customer happy, so the price never uploads or change the conditions of your rate unless it is an automatic and free improvement. Therefore, if you have hired the team that has eliminated, you can continue enjoying it, at the same price and with the speed of 300 Mbps. The competition does offer 300 Mbps. O2 is a very important actor not only for Telefónica, but for the Spanish market. And we have already seen on several occasions that, when O2 takes the first step, others usually move file. But that the panic does not travel, for the moment, there are still several 300 Mbps options for that price (or even less): In areas with own coverage, Digi It offers 300 Mbps + mobile 25 GB for 13 euros per month (15 euros if you want 50 GB). In areas where there is no smart fiber, DIGI proposes the same thing that has just eliminated O2: fiber 300 Mbps + mobile 50 GB for 30 euros per month. Lowi It has a pair of combined with 300 Mbps fiber for 30 euros per month. One with a 50 GB mobile line (like the rate that has removed O2) and another with two mobile lines of 25 GB each. Pepephone It gives the possibility of hiring 300 Mbps + Mobile fiber with 50 GB cumulative for 30 euros per month. But attentive to its next movements, because Pepephone is usually One of the first to imitate O2. Moremobile It also maintains a 300 Mbps + mobile fiber rate with 40 GB for 29.90 euros per month. O2 moves away from the low cost. Since its launch, O2 has offered much more competitive prices than its sister Movistar. And many expected Telefónica to be even more aggressive with O2 after have been released from regulatory obligations that limited their commercial capacity. That is why this movement has caught us by surprise. Now you can’t have fiber and mobile with O2 for 30 euros per month. If you want O2, you have to pay a minimum 35 euros. That amount enters its reasonable price policy, but it moves a lot away from the cheapest proposals of many of its low cost rivals (read Digi). With Murtra in command, one of the unknowns is which strategy will continue with O2. And who knows, perhaps the objective of O2 with this change is precisely that: to move further away from the concept of low cost that, for many, is synonymous with poor quality.

Spanish wine is going through an existential crisis and for producers the problem is simple: too cheap

by

The end of drought has shaken the pendulum of agricultural production, taking ahead the hopes that many had in this harvest. The productivity recovery It has arrived accompanied by a decrease in the prices of a variety of products in the sector. Among them, the grapes used for the elaboration of various types of wine. Protest in front of AECAVA. A few days ago, grape -producing farmers from different communities They organized a protest In front of the headquarters of the Association of Cava (AECAVA) Association in Sant Sadurní D’Alcoia, Barcelona. They did it in order to demand sufficient prices to cover, at least, production costs. 20% more grapes. The protest occurred while the harvest of some of the grape varieties began. The sector estimates that this year will be an increase in grape production, with some farmers calculating a 20% increase With respect to the 2024 harvest. This would be the effect of the recovery of the sector after a drought that affected very diverse crops and left several crops on the edge of the collapse. The situation is now very different thanks to the rains we saw between the past autumn and this spring and even in part of the summer. Double edge weapon. Despite this, this improvement threats becoming a double -edged sword at the fall in prices that the agricultural sector now denounces. The increase in production and static demand involves lower prices, so much that the sector fears not being able to cover production costs. Almost at half price. As explained from the Valencian Association of Farmersthe first offers that wineters have received this year for the conventional grape kilogram is € 0.45, € 0.50 in the case of the grape for the production of “ecological” wine. These figures would represent a price drop of about 50% compared to last year’s prices, € 0.87/kg in conventional grapes and € 1/kg in “ecological” production. Harvest recovery (something we are Seeing in various crops) It would be the reason for this collapse in prices, but producers warn that this recovery does not affect all crops. The field in areas such as the Valencian Community or Extremadura, stand out, maintain a limited yield at 10.5 tons per hectare. A recovery that is not so much. From the winemaker, emphasis is placed on the so long -awaited harvest recovery after drought is not, much less, assured. Some diseases that affect the vine, such as mildewthey are putting a harvest still in the process of maturation in some regions. To this we must add the effects, even to be determined, of a especially intense and lasting heat wave. A heat wave capable to put at risk the process of maturation of plants but has also come accompanied by a series of fires Especially devastating in areas such as Galicia, Extremadura, and Castilla y León.

A simple gene can send a divine punishment to the snails: turn them into “left -handed”

by

It is estimated that Something more than 10% of the world population is left. Today, this does not usually involve greater inconveniences, but there are animals that have a more problematic asymmetry: snails. Left -handed snails. Most snails share the direction in which their snail draws its spiral characteristic that revolves in the direction of the clock needles. But there is a very small population of snails whose shells develop in reverse. The reason It seems to be In a small genetic variation. The snails that develop their shell symmetrically to the rest are usually called them as “left -handed snails”, but if we had to look for a more precise human analogue we tended to go to the condition to which which We call SITUS INVERSUS. People with this condition, also of genetic origin, develop one or more organs on the “incorrect” side, for example they can have the heart to the right and the liver to the left. This condition occurs in around one person in 10,000 and rarely generates disorders, but in the case of these mollusks, the investment of their snail can cause problems, for example, making it difficult to reproduce these animals. A vital gene. Understanding the genetics responsible for change in these animals is important since it can give us clues about the evolution that was modeling the different genera and gastropod species. According to Explain the team Responsible for discovering the main gene involved in this differentiation, throughout the evolution, these changes resulted in the appearance of new species, something striking when it comes to mutations that hinder reproduction. Laboratory snails. The team conducted its study with a variant of snails of the species Bradybaena Similaris. The variant has the characteristic of presenting a high prevalence of “left -handed” snails, almost half of the specimens are born with this characteristic. The team compared the genes of the mice born with shells that turned to either side. They discovered that the main difference was in a gene, Diaph, but not in the gene itself but in its expression. The details of the study were published In an article In the magazine Zoological Letters. Jeremy’s curious case. Perhaps the most famous snail to present this anomaly was a British snail nicknamed Jeremy in honor of politician Jeremy Corbyn, the leftist politician who was twice a candidate for prime minister in the United Kingdom. Jeremy was the protagonist of another investigation whose results postulated an alternative hypothesis to genetics based. The team responsible for the study concluded, after gathering numerous specimens such as Jeremy so that they could reproduce between them, that the change obeyed external forcesnot by genetic inheritance but for accidents in development. The study, Posted in 2020 In the magazine Biology Lettersreminds us that we will still have to investigate these mollusks, their genetics and their development, if we want to know exactly what phenomenon is behind this unique characteristic of a small amount of snails and, above all, of its implications.

We are far from getting the pill that can replace food. The reason we may not get it is very simple

by

Today we can find a huge variety of Nutrients in the form of pill or in a similar format: vitamins, minerals and other compounds that our body generally obtains from food, in a more “practical” format. Some of these pills in fact incorporate a wide variety of these nutrients. This leads us to raise an issue: why not everyone. Is it possible to concentrate all micro- and macronutrients, and all the energy contribution that our body needs in a simple format? And if it is, are we close to achieving it? If someone hoped that the answer to this last question was something different from a resounding “no”, he was wrong. To understand why it is so difficult we have to understand a key detail: not all nutrients are the same and some simply do not fit in a single pill. The first thing we should know for understand the great difficulty to which we would face if we wanted to create A pill to feed It is how we classify nutrients. We usually distribute them into two groups. The first is that of macronutrients that covers three categories: fat or lipids, carbohydrates, and proteins or amino acids. The second, that of micronutrients, which covers the vitamins and minerals that our body requires for its function. The difference between the categories can be intuited by name (and advances the great reason why it is difficult to concentrate the food in a pill), is the amount. We can see food as a mechanism of our body to obtain two things. The first, chemical elements and compounds that you need in your daily function such as amino acids, minerals or vitamins. The second is energy, which obtains mainly through two key macronutrients: carbohydrates and fats (although our body can “recycle” its own proteins as an emergency energy source). Energy is the main problem, and even the most energy concentrated foods, FatsThey require relatively large volumes to be able to provide us with the energy we need (Between 1,600 and 3,000 calories a day in adultsdepending on our body and our habits). The idea of lipid supplements It is not new, but concentrating the necessary amount of fat to replace a meal in a single pill (in which we would also have to include other compounds) does not seem viable, so in the best case we would become dependent on the consumption of several pills to consume throughout the day. “Human beings are never going to eat pills such as food … pills can never be made in a way that contain enough caloric volume,” he explained in an article published in 1936 in the Jefferson City post-tribune (according to He collected more recently The British chain BBC) The professor of the University of Comumbia Milton A. Bridges. “Experfically plausible to provide all the necessary vitamins and minerals in a meal in the form of a pill. But you cannot achieve calories if it is not eating food.” We still have no food in pill but we do have products that try to offer us all the micro and macronutrients that our body needs in a more bulky formatthe milkshake. Slopes of this type are not new: a decade ago they began to popular formulas Like Soylent or Joylent. Is it possible to subsist and stay healthy with these formulas? We do not know, but there are two reasons that lead us to doubt. The first is that human nutrition is very complex. We know a lot about it but it is possible that our bodies require traces of some micronutrient that we have not considered. This is not necessarily the case, but it is a possibility. To know this we would have to put this type of test formulas in rigorous experiments and long term. Something is complicated today. The second issue has to do with the diversity of our bodies: people of different age, sex or body mass would need specific formulas for adapt to your body’s requirements. Even controlling these variables we would also find a huge diversity caused by health disorders and conditions, habits and daily activities, and other factors very difficult to introduce if we would like to customize the pills or The smoothies To consume. Reducing our diet to a series of pills would undoubtedly have their advantages. But it would be difficult to make us lose, as a species, our taste for gastronomy. This way of feeding ourselves is today science fiction and for many surely of the subgenre focused on dystopia: after all, these formulas, practices on a day -to -day basis, eliminate the agency and the feeling of having free will. This does not mean that these options could not have their niche, for example facilitating food in Interplanetary trips or in other contexts in which access to food could be more complicated.

If the question is whether Spain can deny its bases to give air support to Israel, the answer is not so simple

by

And suddenly, Spain. Actually, and as we will see, the country’s geographical situation makes it a kind of “technical stop” for the different military conflicts in which the United States has been. The war that is taking place In the East It is another chapter, but with the exception that, quite possibly, Spain will not enter. What raises a logical question: could it refuse to use its air bases? Reinforcements from Spain. First the news. Within the framework of the growing military escalation between Israel and Iran, the United States has discreetly intensified its deployment in the Middle East with the help of key infrastructure in Europe, including Bases in Spanish territory.
